Good To Know

Q: Is this an original Sea-Doo part? A: No. It is an aftermarket replacement chain that cross-references OEM number 420898044, so verify fitment on your machine before ordering.

Q: Can I replace just the chain? A: On many rebuilds the tensioner and guides are replaced at the same time for best results. Check your service manual for the full list of related parts.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
